How much does a sunroom cost? What is a sunroom?
How much does a sunroom cost? A sunroom, also called a glass room (foreign name: winter garden), is a non-traditional structure made of glass and metal frames designed to enjoy sunlight and connect with nature. Sunrooms are favored by style-conscious people at home and abroad. In North China and Shanghai, sunrooms are a rapidly growing industry, designed and built according to site requirements and personal preferences, with interiors decorated to taste. Balcony or terrace sunrooms connect to the living room, so visual continuity matters—the overall tone should match the building style as closely as possible.
How much does a sunroom cost? What are the development stages of sunrooms?
How much does a sunroom cost? Sunrooms can be divided into five development stages by material and construction method: pure wood, pure steel, aluminum curtain wall, and steel-aluminum structures.
1. After Columbus discovered the New World and before the Industrial Revolution, many tropical plants, flowers, and fruits entered Europe. Europe's cold climate could not support their cultivation, but royalty and nobility enjoyed them. Skilled royal craftsmen built greenhouses to meet their demands. Later, people found these greenhouses full of sunlight and greenery could not only grow tropical crops but also serve as special spaces for leisure, entertainment, family gatherings, and studios.
2. After the first Industrial Revolution, at the 18th-century London World's Fair, Britain built an 80,000 m² pavilion—pure steel and glass—as the pinnacle of early steel sunrooms. Mass steel production further expanded early sunroom applications. Steel sunrooms appear in films such as The Sound of Music and The Time Machine.
3. In the first half of the 19th century, with high-rise construction, aluminum—easy to form, lightweight, and strong—was used for doors and windows. Modern lighting towers and ceilings were also aluminum. As living standards rose, sunrooms became essential for middle- and upper-income families in developed countries. Abroad, sunrooms became a lifestyle. With rising incomes in China and growth in villas and duplex homes, sunrooms became an unstoppable trend. People built sunrooms to their taste—natural wood or industrial steel. Aluminum became mainstream due to standardized curtain wall materials.
4. Steel-aluminum sunrooms mainly use steel frames and aluminum profiles. Some sunrooms are too large for aluminum alone; steel's high strength and weldability suit large builds. Domestically (especially Shanghai), sunrooms were new and costly, so steel-aluminum composites reduced cost—steel for structural strength, aluminum for surface finish. Aluminum-clad steel sunrooms fit early-21st-century China: high strength, low cost, but long construction cycles, lack of standardization, many uncontrollable factors, and quality variability.
